I'm developing javaee aplication with JSF/Primefaces.

I needed to secure my application. I did that with:

<security-constraint>

        <web-resource-collection>

            <web-resource-name>APP</web-resource-name>

            <url-pattern>*</url-pattern>

            <http-method>GET</http-method>

            <http-method>POST</http-method>

        </web-resource-collection>

        <auth-constraint>

            <description>MYROLE desc</description>

            <role-name>MYROLEAccess</role-name>

        </auth-constraint>

        <user-data-constraint>

            <transport-guarantee>NONE</transport-guarantee>

        </user-data-constraint>

    </security-constraint>

<login-config>

   <auth-method>BASIC</auth-method>

</login-config>

However when I defined a custom error-page for error 401

<error-page>

   <error-code>401</error-code>

   <location>/error/401.xhtml</location>

</error-page>

I got:

   Problem occurred while serving the error page.

    java.lang.IllegalStateException: Must call associate() before calling activate()

        Truncated. see log file for complete stacktrace

`

and the browser presents HTTP ERROR 500.

I'm using weblogic 12.1.3 and java 7.

I tried with weblogic 12.2.x and java 8 and it works.
What's wrong here?
Can you help me? If I don't map the error it asks for the credentials, otherwise it goes imediately into Error-500.
